Chengdao Oilfield is located in the modern Yellow River underwater delta, where the seabed strata are complex, and the sediment silt and silty clay have great interbedding changes. In recent years, an increasing number of jack-ups are installed and removed in the same wellhead or similar wellhead. There are risks of sliding pile, punch-through, and liquefaction and subsidence in the area where piles are repeatedly inserted and pulled out on offshore moving platform. Aimed at the risks, preventive measures are analyzed to reduce the risk of pile driving on jack-up platforms.
